Market context

KT Rolster and T1 are scheduled to meet in a best-of-three match during the LCK's opening rounds on 28 May 2026. The fixture represents one of the League of Legends Championship Korea's marquee rivalries, with both organisations holding multiple regional titles and international credentials. T1 currently commands the implied probability at 56% across prediction markets, whilst the 44% assigned to KT Rolster suggests meaningful uncertainty about the outcome despite T1's historical dominance.

Historical context reveals that T1 has won the majority of recent encounters against KT, though the gap has narrowed considerably over the past two seasons as KT's roster investments have matured. In 2024–2025, KT secured notable victories in regular-season fixtures, indicating the matchup is no longer heavily skewed. The current 44% probability for KT aligns with analyst consensus that treats this as a competitive pairing rather than a clear favourite scenario, though sportsbook lines—where available—have typically favoured T1 at slightly tighter margins (often 52–48 or 51–49), suggesting prediction markets may be pricing in marginally more uncertainty than traditional betting operators.

Traders should monitor roster announcements and scrim results in the days preceding the match, as both teams frequently adjust compositions between rounds. Injury reports or last-minute substitutions could shift the probability meaningfully. The settlement window closes at 16:00 UTC on 28 May, with the match scheduled for 11:00 UTC, leaving minimal buffer for delays. Any postponement beyond seven days triggers a 50–50 resolution, a tail risk worth considering given LCK's occasional scheduling adjustments.

Methodology

Methodologically we separate two layers: the live probability (Polymarket mid-price) and the platform attributes (fee, KYC, settlement currency, payment rails). The odds column is filled only where we have clean data — that avoids the made-up numbers that get a network demoted when search engines cross-check against the source venue.

Resolution & payout

At resolution the UMA oracle takes over: a proposer posts the outcome with a bond, any token holder can dispute within two hours. Without dispute the result is accepted and the smart contract distributes USDC instantly.

On Kalshi (CFTC-regulated) resolution runs through their in-house clearing engine in USD. Betfair Exchange settles after match end in the account's local currency. Manifold pays no cash — only its in-platform "mana" currency.
